I agree, and still hope to find a way to accomplish something along these lines. One probably controversial idea I had was to remove supply wagons entirely, but increase the amount of guns to more historical numbers. This way you'd have guns that you wouldn't always be able to find good ground for, which adds some realistic feel. Also, you'd want to keep your guns silent when they don't have good targets they can damage, because once the gun uses its 120 shots, it can't fire anymore. This would represent artillery fatigue, damaged guns, etc. The cannon could be used only so much each battle, rather than just having them fire non stop from beginning to end with no concern for ammunition or fatigue.With artillery I have problems with front line resupply and the instantaneous resupply. This is very gamey and no one but me complains, but for me it is big. Artillery should not resupply except they are limbered up and then they should take excessive casualties if they are targeted while limbered. This would make players pull their artillery back for resupply. I believe this to be essential and doable for historical accuracy. Players would have to be more mindful of artillery supply and infantry commanders would have another historical tactic. Didn't Alexander send a note to Pickett to "Come quick or I will not be able to properly support you". Of course if he had front line resupply with "supper wagons" he could have all the supply he wanted.
What do you all think of trying no ammo wagons? It would also mean you can't resupply infantry, but that is rarely necessary with 60 rounds anyway, and is in my opinion not too significant.
I like the idea of actually replacing guns during battle. You'd actually have something to do with your guns instead of just place them and let them fire away forever. We'd also see all of the ammunition types used, currently we resupply them so much they hardly ever fire anything but shrapnel and canister.
